near the lowery end of the frame the sheet is provided with entrance orifices 7 An auxiliaryY frame 8 comprising side `bars `9 and top andbottom bars 10 and 11 is secured'upon the outer faces of theside andbottom bars of the frame 1 and is approximately and preferably three-fourths the length ofthe framel. A sheet 12 of foraminous material is secured upon the .f'auxiliary frame 8 as is the sheet 6 but nearthe outer-faces of the bars and will hereinafter be referred to as the outer sheet. Near `the lower end of tliefsheet 12 are formed enland intermediate sheets, in engagementwith said sheets and in alinement with the top bar'of'the frame 8. The partition bar 15 is provided with openings 16 which` extend throughthe bar, and are 'preferably larger at their-lower ends than at their upper` ends and'open upon opposite longitudinal 4sides of thebar.y 'The iiitermediate sheet is ex- "tended above the partition bar 15 andf then bent over `rand-extended down between the bar and innery sheet and secured in such' positiontoform acompartment 17 which has y connnunication with the spaces between the iiiterme'c'liate and iinner and outer sheets.

To provide for communication of the compartment '17 with the space between the in- `termediate and outer sheets, the top bar 10 oftherauxiliary framelfS kis recessed as at 18 and said recess communicates with one ofthe openings in the bar 15 through an opening 19 forined in the intermediate sheet. `The recess 18 decreases in size near "theupper edge of the barf10 and as said bar 10 closely f engageslthe intermediate sheen-the flies are prevented from 'escaping by crawling' up between 'the bar 10 and intermediatevsheet. The openings'l inthe bar'l are preferably q=\/-shapedwith* the larger ends lowermost so asto'gi've sufiicient'light'to `attract the flies and cause them to `crawl upwardly therethrough.'y t y l `provide a semi-circular `cagev21wh1ch r"consists"ofsemicircular end plates@ about the peripheries'of which is secured a sheet of foraminous material 23. 22 are connected withone another byv upper and lower connecting bars 24 and 25 and said lower bar 25 is designed to rest upon the upper bar 10 of the auxiliary frame 8. The foraminous material 23 covers the bars 24 and 25 and at a point between said bars is provided with preferably a single orifice 26. The material between the bars 24xand 25 engages the side and top barsof the main frame and as it is spaced fromthe inner sheet 6 forms a free space which is comi municated with the compartment 17 by prefl 31 pivoted on said .end wall.

erahly al single orifice 27 formed in the u pper side of the compartment 17. The flies upon entering the spaces between theupper 1 portion of the inner sheetand cage will find access to thecage through the single orifice 26 formed in the inner wall of said cage, said orifice 26 being preferably located near Athe Vupper edge of the inner wallof the cage.

Y Hooks 28 are secured upon the outer faces vof the end plates of the cage and cooperate with screw-eyes 29'carried upon' the outer sides ofthe side bars 2 and 3. The hooks and eyes Vhold the cage in close 'engagement frame. y

y A cleanout opening 30 is formed in one end plate of the cage and is closed bya door The opening is of sufficient size to enable insertion of a suitableinstrument into the cage to effect the removal ofthe flies therefrom.

Y Y Connected with the lower part of the cage at a point near one of the side bars of the auxiliary frame is adepending cleanout tube or pipe 33. This pipe may'be of any length desired and is preferably extended to a point below the main frame so that the flies may be caused to drop upon the ground orV into a receptacle, not shown, placed beneath the tube. As the wind blows through the cage the fliesv therein which have died from confinement will be blown into the tube rand lwill then drop. therethrough.

Y or inner and outer sheets, through the openings 16 inthe vpartition bar 15 and also through theA recess 18 andthe openings 19 .in the intermediate sheet into the partition bar opening 16 which communicates therewith and fromthence into the compartment 17. The flies will then crawl through vthe The end plates.

Vthe preferred form.

single orifice 27 in the upper end of the compartment 17 and into the space between the cage and inner sheet 6 and from thence through orifice 26 into said cage. cage has become' sufficiently filled it may be removed, ifrdesired, and the flies shaken therefrom through the tube 33 and the cleanout opening 30 vin one end plate.

Referring particularly to Figs. 9 to 1 wherein I have illustrated a modified form of screen, 34 designates a main frame comprising side bars 35, 35" and top and bottom bai-S736 and 37. Secured to the bars is an inner foraininous sheet 38.

AAn auxiliary rectangular frame 39 is secured upon the frame 34 andl is of substantially the same size and arrangementas is the auxiliary frame in the preferredv form.

An outer sheet of foraminous material 40 is secured between the frame 39 and the main frame 34. A horizontal partition bar 41 is positioned between andin engagement with the faces ofthe inner and outer sheets and secured at its ends to the side bars of the mainframe. VThe cuter sheet is extended above the partition bar and is'bent over and then extended down between the inner sheet and the partition bar'and secured in such position to provide a compartment 42 which corresponds to the compartment 17 of On the outer face the horizontal partition bar 41 is formed with recesses 43 extending from the upper to the After the lower edges thereof and which communicate the space between the inner and outer sheets with the compartment 41. 3 The recesses 43 are preferably larger at their lower ends so as to induce the flies to' crawl upwardly by giving plenty of light at points where .the recesses arefformed. The ends of the compartment 42 are closed bythe side bars of the frame 34.

I provide partition means between the inner and outer sheets to cause the flies vto crawl upwardly into the compartment 42 and prevent them from crawling through the inner sheets and escaping out through the outer sheet or vice versa. Thepartition meanscomprise preferably a vertical bar 44 .that is secured at its lower end to the lower bar of the mainframe and at its inner end to the horizontal partition bar 41'. This l partition bar extends vertically near the side bar 35 of the main frame but is spaced therefrom and engages the inner and'outer Y the main frame between and in engagement with the inner and outer sheets. These bars 45 and 46 are arranged one above the other and divide thespace between the inner and outer sheets into three sections. .The inner Diagonal partition bars V45 and sheets so as to provide a'vertical space or and outer sheets are alternately provided with orifices 47 relative to the sections so as to prevent the iies from crawling through the inner sheet orifices and escaping through the outer sheet orifices. On opposite sides the vertical partition bar is provided with recesses 48 and 49 which communicate the spaces between the diagonal partition bars with the space between the vertical partition bar and frame bar 35. The latter space is communicated with one of the compartments 42 by the recesses in the horizontal partition bar.

A cage designated 50 and identical with the cage 21 in the preferred form is secured to the upper end of the main frame and is arranged for communication with the compartment 42 by an opening 43 formed in the upper end of said compartment.

The inner and outer sheets are provided with cleanout openings 51, 52, 53 and 54 which are located respectively above the bars 46, 45 and lower bar of the auxiliary trame.k

Pivoted doors 55 normally close the openings and said openings are located at such points that will enable dead flies within the spaces provided by the partition means to be easily removed.

In practice I have found that the form of my invention illustrated in the drawings and referred to in the above description as the preferred embodiment is the most eflicient and practical, yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in construction, proportion and arrangement of parts may be resorted to when required without sacrificing any of the advantages of my invention as set forth in the appended claims.

I claim:

1. A combined iy trap and window screen comprising a window screen frame, inner and outer sheets of foraminous material secured to said :trame in spaced relation to one another, each of said sheets having fly entrance orifices near its lower end, al cage carried by said frame, partition means bey tween the sheets to prevent flies from crawling through both sheets and for inducing the flies to crawl upwardly, and means for communicating the cage with the spaces between the inner and outer sheets.

2. A combined fly trap and window screen comprising a frame, inner and outer sheets of foraminous material secured to the frame in spaced relation to each other, a plurality of partition bars mounted between and in engagement with the sheets and dividing the space between the sheets into a number of sections, certain parts of the inner and outer sheets being provided with entranceV oriices for communication with certain of the sections of spaces between said inner and outer sheets, a cage, and means to com1nunicate the cage with the spaces provided between the inner and outer sheets.

3. A combined fly trap and screen comprising a screen frame, inner and outer sheets of oraminous material secured on opposite sides of the frame, each of said sheets having fly entrance oriiices 'formed therein, partition means located between the screens to prevent the iiies from crawling through one screen and out through the other and for inducing them to crawl upwardly including a horizontal partition bar mounted between the sheets, a compartment independent of the sheets arranged above the partition bar, said partition bar having openings therein communicating said compartment with the space between the sheets below the partition bar, and a trap mounted upon the frame and having communication with the compartment.

In testimony whereof I have hereunto set my hand at Los Angeles, California, this 8th day of May, 1915.
